    LG microwave oven LMVM2075SW, fourteen months since purchase, some buttons on the control panel respond when pressed, while others do not.

    Only the occasional button will work on the keypad, and it changes as to which button that is.

    the control panel just stopped working and only 2-3 buttins work when pressed. Can't use the microwave because not even the start button works.

When you say the control panel does not work, do you mean it does not show a display?

Or is there a display but there is no response when you press the pads on the keypad?

In either case, I would say it's a problem in the control assembly, whether it needs a new keypad or the circuit board needs to be repaired, we can probably help you.

We regularly repair these control units for customers nationwide by mail for $39.95 postpaid in most cases in about a week.

Feel free to contact me directly (and please remind me of your model number) for more information & help.

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

How to find fuse on LG lmvm2075vm

Some new machines do not have a fuse, unplug microwave, remove top "several screws" look to the right where the keypad control board is, look down and you should see a small circuit board, look for a fuse that is clipped in and pop it out, replace with same current rating and assemble microwave before test, "lethal voltages present"

LG microwave oven that has a 2-level (Low & High) that lights the cook surface. The High level light does not work?

There could be a number of issues, A schematic would be of great help to determine how the lights operate / how they are controled. They might be controled directly off the control board, or via a step down transformer. The lights might have two filiments for low & high. There could be two light bulbs, where one is on for low & two for high. A two position switch could be bad for the high position.

My LG 2075 microwave touch panel stopped responding. After unplugging for the night, it now flashes locked and does not respond to any of the keys.

The touchpad is bad most likely. You can go to and they will have the part. The part will come with detailed instructions for installation.

LG LMVM2075 Microwave Control panel does not work

The keypad has failed and it is available as a part of a new outer door panel, whose part number is 383EW1A130E for $103.19 plus shipping.

You can get it from Encompass here or you can call them toll-free at 866-779-5835.

For disassembly info, you can see the service manual at our site:

It does not contain part numbers, so you will need to contact Encompass.

Direct spraying of cleaners on the keypad and steam from the cooktop can damage the controls.

I always recommend that you spray non-ammonia cleaner on a soft cloth (not a paper towel which can scratch) and gently wipe the keypad.

And I always recommend that you use the vent fan whenever you're cooking on the stove top to keep heat, steam, and grease out of the controls and door panels.

LG microwave LMVM2075ST panel started acting crazy after I cleaned it. Will not do anything if I push a button except beeping noises. Any suggestions as to what is going on with this machine? Should I try...

liquid probably has entered keypad laminate; causing a short. unplug unit, direct warm hairdryer to entire keypad; plug back in; and hope for the best. if no luck; replace keypad. also never spray anything directly onto keypad; always clean with a moistened towel with light force.

Cooktop light not working

We see this a lot. The problem is on the control panel, which we regularly repair nationwide for $39.95 postpaid.

This light failure often occurs when a bulb goes out and the filament shorts, or when the bulbs are removed or installed without first unplugging the oven from the power line. Either can cause such a failure on the controller.

If you or a friend decide to look into it, we have critical safety information and disassembly information at our site, linked here on Fixya:
